网络计划技术探讨——虚工作的时间参数是否需要计算

Discuss on network technique——the time parameters of dummy activity should be calculated or not

虚工作在网络计划技术中起着非常重要的作用 ,作为一种特殊的工作 ,其时间参数是否应当如常规工作一样计算呢 ?这个问题是值得加以探讨的 ,因为众文章或书籍对这一问题处理得较为混乱。本文通过双代号网络与时标网络的对照及论证 ,以期得出统一。

Dummy activity plays a very important role in network technique.As a special activity,whether the time parameters of dummy activity should be calculated or not?It is a problem worthy of be discussed,because in many concerned books or papers,this problem is confused.With the demonstration and comparison of activity on arrow network and time scaled network in this paper,proper clusion is expected to drawn.
